Hello, I have a Canon MP 490 and I just got an Airport Express. I was able to set up the printer with it connected via USB to my MacBook Pro. However, I've been searching around the forums and google for a while now and I can't seem to make it wireless. I have tried looking around the Airport Utility and didn't find anything. I tried messing around with the settings under Printers and nothing. Is there a way to set up this printer without leaving it connected to the MBP? Thanks in advance!
